There exists a single massive black hole core, connected to all event horizons in the universe. Each half of the core is the mirror image of the other, rotated by 180 degrees. Matter enters through event horizons connected to the propagation front of the matter half of the core's structure. Similarly, antimatter enters through the respective event horizons connected to the propagation front of the antimatter half of the core's structure.
